Title: Tower crane erection system - has hoist rope reeved round pulley block attached to erection winch rope
IPC: B66C23/34
Filed: 1973-07-03
Abstract: The hoist rope (1) is reeved round a pulley block (3) so as to form two runs, and the pulley block is attached to the erection winch rope (4). The weight of this pulley block keeps the hoist rope right, even whent he hook is lowered to touch the ground. The hoist rope tends to raise the pulley block (3) and the erection winch rope (4e raises the tower by means of the tension exercised between the base (6) and rope (4) by pulley system (7). a load on the hook produces a lower but proportional load on the pulley system (7).

Title: Anti-skid wheel brake - reinforced by electro-magnetic brake which senses wheel locking by reducing current
IPC: A61B5/16
Filed: 1973-07-31
Abstract: The conventional wheel brakes are reinforced by electromagnetic brakes fitted to at least two wheels. The rotating wheel forms the rotating permanent magnet while the stator is magnetised through battery powered windings. The induced current is shorted through a shunt whose value is such that it provides a constant current until wheel blocking nears, when the current drops rapidly. The dropping current is also used to modulate the mechanical braking effect, and acts as a simple type as anti-skid braking control.

Title: Bottom blown converter - with two oxygen supplies through tuyere jet at different pressures
IPC: C21C5/34
Filed: 1974-03-28
Abstract: Bottom blown converter using an oxidising gas at high pressure, whereby the pressure is kept below a limit set by the level required to keep a practicable gas-metal contact time, sufficient to complete the refining reaction, and whereby a second jet of oxidising gas is supplied, using an annular jet surrounding the first, at a low flow rate and a higher pressure than the main jet. In to this second jet is also supplied a fluid, protective w.r.t. the refractory lining around the tuyere. The invention prevents the build up of masses of metal around the jet, which would block it.

Title: Ultra-centrifuge for isotopic sepn - has pleated vertical cylindrical bowl suspended by ball and socket joint
IPC: B04B9/12
Filed: 1974-04-05
Abstract: The bowl of a centrifuge is vertical and suspended by a ball and socket joint allowing it to rotate and at the same time forming a bearing and thrust-block. The lower end of the bowl is guided by a bearing the outside runner of which is centred by 3 helicoidal springs symmetrically spaced,which offer resistance to sideways movement. Both ends of the bowl are of a hemispherical crown thinned at its edges to the thickness of the bowl, and joined to the bowl at a tangent or in its extension. The cylindrical bowl of the centrifuge is pleated transversally to absorb vibration. Between the ball and socket joint and the upper hemispherical end of the bowl is the induction drive motor which rotates the bowl. Reduces failure of bowl by metal fatigue due to vibration while still allowing the prodn. of larger bowls.

Title: Siphon type odour seal for sewer inlet - has vert tapered inlet pipe in water filled vessel less deep than inlet pipe
IPC: E03F5/04
Filed: 1974-05-10

The smaller extremity of the pipe locates in a water filled vessel (2) extending for about half the inlet pipe height. The bottom of the pipe (1) is spaced somewhat from the vessel base so that inflowing water passes into the sewer by overflowing the upper edges of the vessel and an effective hydraulic seal is thus formed. External gussets (3) on the inlet pipe outer walls locate it w.r.t the lower vessel.
Patent FR-2280042-A1 (FR)
Title: Cooling of a gas mixt - by countercurrent contact with a recycled mixture, useful for cooling natural gas
Inventor: SCHLATTER RENE
IPC: F25J1/02
Filed: 1974-05-31
Abstract: A process for cooling a gas stream, e.g. a natural gas, consists of transferring heat from the natural gas to a mixt. which is recycled. The mixt. is condensed at high press. by an external refrigerant giving a first condensate. A second condensate is obtd. at medium press. by counter-current contact with a first recycle stream. The vapour above the second condensate is cooled by counter current with the first recycle stream and divided into two streams. One is expanded to medium press. and forms the first recycle stream. The other is expanded at low press and forms a second recycle stream, which cools the natural gas and is then compressed to medium press., joined to the first recycle stream, and compressed to high press. The first and second condensates pass through the second recycle stream, are expanded and join the second and first recycle streams. The compression from the medium press to the high press. takes place in two substages. The mixt., at intermediate press. is partially condensed by an external refrigerant to give an intermediate condensate. This condensate passes through the second recycle stream, is expanded, and is divided into two parts, which are added to the first and second recycle streams resp. Pref. the compsn. of the recycled mixt. and the intermediate press. are adjusted so that the mean mol. wt. of the intermediate condensate is 45-65. The external refrigerant is a vaporised fluid, e.g. propane. Process is efficient and economical.

Title: Spraying of fine coatings onto prods. in a tank - without wasting coating material or spoiling coating
IPC: A23P20/12
Filed: 1975-03-11
Abstract: Spraying method is carried out by placing a trough contg. the prods. to be sprinkled beneath a sprinkling cover, applying the cover sealingly over the trough, and injecting a given quantity of sprinkling material into the cover by means of a distributor. Press. is generated within the cover to create turbulence which allows the sprinkling material to be deposited on the prods. The press. is then modified so that undeposited material remains in suspension within the cover. The cover is finally raised to allow removal of the trough and positioning of another trough. The cover may be supplied with the material while the material is being deposited. A fan may be used to regulate the different pressures within the cover as a function of density of the material and quantity of material to be deposited.
